Near‐field scattering centre modelling for complex targets
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2657-2666, December 2024.In this paper, the authors presented the near‐field scattering centre model with the dependence description of radar distance. The model can be used to quickly calculate the near‐field scattering field and radar image features of complex targets. Abstract The parametric scattering centre (SC) model of the target has been widely used in the rapid ...

Experimental Synthetic Aperture Radar with Dynamic Metasurfaces
, 2017 We investigate the use of a dynamic metasurface as the transmitting antenna for a synthetic aperture radar (SAR) imaging system. The dynamic metasurface consists of a one-dimensional microstrip waveguide with complementary electric resonator (cELC ...

A novel multi‐target TBD scheme for GNSS‐based passive bistatic radar
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2497-2512, December 2024.The paper presents a novel approach to enhance low‐altitude surveillance in urban and suburban areas using GNSS‐based passive bistatic radar systems. Despite challenges such as weak signal power budget and complex multi‐target tracking, the proposed method introduces a track‐before‐detect (TBD) strategy with a DCCF‐based cluster centroid extraction ...

HRRPGraphNet: Make HRRPs to be graphs for efficient target recognition
Electronics Letters, Volume 60, Issue 22, November 2024.Conventional techniques for High‐Resolution Range Profiles (HRRP) target recognition frequently encounter difficulties due limited data under non‐cooperated circumstances. We propose a novel use of graph‐theory of HRRPs and convert traditional sequence‐based recognition into a sophisticated graph classification task to achieve efficient target ...
